Improvement in cloth-measuring machines



UNITED STATES PATENT GEEICE.

JOHN M. PALMER, OF NASHVILLE, TENNESSEE.

IMPROVEMENT IN CLOTH-MEASURING MACHINES.

Specification forming part of Letters Patent No. 154,895, dated September 8, 1874 application filed June 8, 1874.

To all whom it may concern:

Be it known that I, JOHN M. PALMER, of Nashville, in the county of Davidson and State of Tennessee, have invented certain Improvements in OlothrMeasuring Machines, of which the following is a specification:

My invention consists in a pair of cylinders, the upper one of which has on its shaft a pinion driving. a toothed wheel provided with pointers and dial -plates for indicating the number of revolutions, and with a projection for striking a lever to sound a bell, the lever being formed with a knife-handle joint, to allow the motion of the rollers to be reversed without sounding the bell.

In the accompanying drawing, Figure l is a longitudinal vertical section of my improved cloth-measuring machine. Fig. 2 is a transverse vertical section taken in the line x of Fig. l. Fig. 3 is a transverse vertical section taken in theline y y of Fig. l. Fig. 4 is a face or end view. A

The upper cylinder, B1, is journaled in stationary bearings inA the main frame A of the machine. On the frontend of its shaft is a pinion, b', which drives a gear wheel, O, on both ends ofthe shaft of which are pointers c1 c2, for indicating on dial-plates D1 D2 the number of revolutions of the cylinder B1. The dia-l D1L is arranged on the outer end or face of the machine, and the dial D2 ou the inner portion of the frame above the cylinder Bl. On the outer side of the gear-wheel O is a stud or pro jection, e, which, as the 4wheel revolves, depresses one end of a lever, F, on the other end of which is a hammer, g, which strikes a gong, G. The lever'F is pivoted to the frame A, and

. provided with a spring, It, for holding it in the position shown in Fig. 3. Between the fulcrum and the point of engagement of the stud e the lever is formed with a knife-handle joint, f, which allows it to bend upward but not downward, so that, when the wheel O revolves in the direction of the arrow, the stud e depresses the lever and strikes the bell; but when the mot'on is reversed, the stud raises the jointed p \rtion of the lever, and passes readily by it wi\thout sounding the bell.

The lower cylinder, B2, is journaled inblocks J J, under which are springs i resting upon sliding bars K K. Thesesprings serve to ing mechanism, is journaled a shaft, Q, carrying a toothed wheel, q, driven by a pinion, r, on a shaft, R, which receives its motion from the wheel O. The shaft Q lcarries a pointer at each end, said pointers revolving outside of dial-plates S1 S2,` arranged beside the dial-plates D1 D2. The pinion r is loose on the shaft R, and is caused to revolve therewith by means of a clutch, t, providedwith a rod,s2, for throwing it out of engagement, and a spring, s, for holding it engaged with the pinion r. The shaft Q is provided with a spring, U, which draws it backwhen the clutch is disengaged.

As the cylinders B1 B2- revolve, when the wheel O and its pointers make a complete revolution the shaft Q is revolved sufficiently to cause the pointers on its ends to indicate the same on the dialplates S S2, and thus register the number of revolutions of the cylinders. By withdrawing the rod s2, and disengaging the clutch, the shaft Q is reversed by the spring o.

What I claim as new, and desire to secure 'by Letters Patent, is-

rIlhe combination, with the cylinders B1 B2, of the gear-wheel C, having a stud, e, the lever F, having the knife-handle joint f and hammer g, and the gong Gr, the whole being constructed to operate as and for the purpose described.
